I was fliping through the chanels last night when something caught my attention on CBC news. Health Canada says it is testing compact fluorescent bulbs to measure potentially harmful ultraviolet radiation and electromagnetic-field exposure levels. It admits something like UAV 3 rays which is worse then Direct sunlight. Im sure this is a concern with lots of people on here who work very closely with large amounts of CFL's and larg wattage CFL's. They say not to spen more than and hour beside one. This is just for household CFL's the big ones say 150watt- 200watt whould be about 3-4 times that. They havent confirmed anything yet, but still makes me uneasy.

Thought we were getting past THAT!
Its mostly whats on the inside of the bulb that is bad. Every electronic device puts out radiation, your computer screen and your cell are good examples. don't sleep in your growroom.
